It is necessary to judge whether it is a malfunction caused by electrical appliances, short circuits, leakage, or the insulation of the switch itself. The best way is to use the disconnect method to narrow the fault range and find the fault point. The ammeter detects the working current of the electrical appliance to determine whether the nominal value of the circuit breaker can still meet the standard!

The total air switch trips in 3 ways:
